Built to Last in Demanding Environments

The TRI-NADO truck vacuum pump features a one-piece, close-grained cast iron casing with heavy ribbing. This rugged construction resists distortion under extreme conditions, extending the pump’s operational life and reducing long-term replacement costs.

Minimized Downtime, Maximized Output

Thanks to ROOTS WHISPAIR™ technology, the TRI-NADO reduces pulsation, noise, and horsepower demands. This means smoother, quieter operation, keeping your fleet productive and minimizing costly interruptions.

Maintenance Made Simple

Closed-end impellers made from high-tensile ductile iron eliminate the need for liquid sealing or lubrication. This not only boosts durability but also simplifies maintenance routines, saving time and labor.

Engineered for Strength and Stability

A 3” diameter alloy steel shaft, flange-connected to the impeller body, delivers exceptional structural integrity. This robust design ensures consistent performance, even under continuous heavy-duty use.

Precision Timing for Peak Efficiency

Alloy steel spur gears, operating in an oil bath, synchronize impeller movement with precision. This reduces internal wear and extends the life of critical components—keeping your truck vacuum pump running smoothly.

Smart Lubrication for Long-Term Reliability

The patented jet spray oil slinger system targets lubrication exactly where it’s needed—on gears and bearings. This reduces friction, lowers heat, and improves energy efficiency while extending component life.
